Comparison of Dose Volume Histogram (DVH) of Simulated Object Calculated by Analytically and Treatment Planning System (TPS): Preliminary Study

Research output: Contribution to journalConference articlepeer-review

Abstract

TPS is the key to the success of external radiotherapy medication, which directly affects the quality of treatment planning and accuracy of dose calculation within the plan. The output of TPS's plan result is in form of DVH curve. DVH is the reference for dose dispersion on the target or healthy organ. Within this research, DVH result from the TPS and DVH result from analytical calculation were compared. The DVH comparison was started by creating a simulation object in form of virtual phantom using Matlab program in various geometrical shapes, which were sphere, cube, and cylinder. The planning on simulation object was conducted using TPS Eclipse. From the result of the plan using TPS Eclipse and analytical measurement, it can be concluded that the highest value difference was on the sphere object simulation. While for the Dmax and Dmin value comparison, the highest difference was in Dmin with the highest discrepancy. This was caused by the voxel size on each measurement. Besides, the dose value of interpolation and voxel determination on the surface of the geometrical simulation object also affected the value of analytical measurement, so it resulted in the higher value compared to the calculation result on each TPS.
